Requirement for submitted registration username $ uname:
1. the name must consist of English and Chinese characters, but the name cannot contain spaces.
2 cannot contain the following special characters in $ arr2
3. it can contain Chinese brackets (")".

 Function checkReg ($ uname)
{
/**
// Write a short
$ Arr2 = array (
'~ ','! ',' @ ',' # ',' $ ',' % ',' ^ ',' & ',' * ',' _ ',' + ', '|', '-', '= ','\\',
'{', '}', '[', ']', ':', ';', '"', '\', '<', '> ',',','. ','? ','/',
''',''','【',']','~ ','! ',' ￥ ','...... ',' -- ','. ',
PHP_EOL, chr (10), chr (13), "\ t", chr (32 ),
);
**/
$ Arr2 = array (
'~ ',
'! ',
'@',
'#',
'$ ',
'% ',
'^ ',
'&',
'*',
'_',
'+ ',
'| ',
'-',
'= ',
'\\',
'{',
'}',
'[',
']',
':',
';',
'"',
'\'',
'<',
'> ',
',',
'.',
'? ',
'/',
',
'"',
''',
''',
'【',
']',
'~ ',
'! ',
'￥ ',
'...... ',
'--',
',',
'《',
'",
'. ',
PHP_EOL,
Chr (10 ),
Chr (13), // \ r \ n
"\ T ",
Chr (32 ),
);


Foreach ($ arr2 as $ k ){
// I used preg_match to make the results messy. Later, strpos (default7 # zbphp.com) was used)
If (strpos ($ uname, $ k )! = False ){
$ Tips = "The registration name cannot contain special characters such as spaces, dots, and commas! ";

Return array (false, $ tips );
}
}

Return array (true, 'OK ');
}

------ Solution --------------------

If ($ s = str_replace ($ arr2, '', $ s )){
// Does not contain special characters
} Else {
// Contains special characters
}
